"Very intelligent" is not simply "a genetic trait" and the extent to which it's genetically determined at all is heavily disputed in at least three mainstream science fields (psychometrics/quantitive psych, molecular genomics, and behavioral genetics).
Doesn't matter, it's still largely genetic.
Probably false. Twin studies had it pegged as high as 80+%, but they were methodologically flawed; you see estimates as high as 50% now and as low as the mid-teens.
